I have a 94 Honda Civic with an F20B turbo.

So when cold the car Runs good and no issues. After it warms up I hear what sounds like a misfire and the rpms drop very low to the point of stallin and my wideband goes super lean from 16 to --. But if i give it gas car still runs good and revs out with no problems.

And ideas on possiblity of issues? Thanks
